摘要： A web of material having a multiplicity of discrete regions or patches spaced apart from each other on at least a first side of the web, and methods of making the web. A plurality of stems extend from each patch. In certain embodiments, at least a portion of the web may be configured to engage the plurality of the stems, and the web may include a breathable (microporous) and/or elastic material. A method of making a web includes providing a web and discrete quantities of a polymeric material. The polymeric material is fused to the web; and a plurality of stems are formed in each of the discrete quantities of the polymeric material to form fastener patches or regions. The discontinuous fastener patches can function as the male component of a hook-and-loop refastenable mechanical fastener.

摘要： An elastic web of material has a multiplicity of stems extending from at least one side of the web. The web includes a first continuous layer of elastic material having a first side and a second side and a second layer of material. The second layer of material has a first side which faces the first side of the first layer and a second side from which the stems extend. The first and second layers of material are joined together. The second layer of material can be formed of thermoplastic material or melt processable polymeric material. The first and second layers of material are melt formed. They are joined by coextrusion or lamination to form a multiple layer sheet on which a multiplicity of stems are formed on at least the second layer by a process such as embossing the stems into the heated web using a patterned roll or mold.

摘要： A laminated composite suitable for use in medical products such as tapes and wraps. The composite includes, for example, a first nonwoven fiber layer, an elastic layer, a melt blown adhesive fiber layer, and a second nonwoven fiber layer. A scrim layer serves as a deadstop, or stretch limit, to prevent over stretching. The non-woven fiber layer(s) and/or the scrim layer form suitable loops for a hook and loop fastening system. The scrim layer in some embodiments is employed to make the composite finger tearable. The melt blown adhesive layer, nonwoven web layer and elastic layer form a breathable, porous elastic composite. Methods of manufacturing the composite are also disclosed.
